High performance jack

ABSTRACT

An electrical connector jack is provided including a body with a support portion and a plug receiving portion defining an opening. A circuit board is mounted to the support portion to position the circuit board relative to the plug receiving portion. The circuit board has interconnecting conductor circuit traces respectively extending from spring contact termination locations. A plurality of terminated spring contact conductors is provided with each terminating at a respective one of the spring contact termination locations, each of the terminated spring contact conductors having a contact zone. A plurality of supported spring contact conductors are supported by the body and extend therefrom. The supported spring contact conductors each have a plug contact zone and a terminated spring contact conductor zone. With contact of the plug contact zone with a plug, the supported spring contact conductors are respectively in contact with respective contact zones of the terminated spring contact conductors providing a transmission path from the plug to the circuit traces of the circuit board.

FIELD OF THE INVENTION

The present invention relates to electrical connectors such as RJ styleplug and jack connectors for communications systems and moreparticularly to such connectors which attain a high level of throughputtransmission performance such as TIA (Telecommunications IndustryAssociation)/EIA (Electronic Industries Alliance) category sixperformance (CAT 6) or higher.

BACKGROUND OF THE INVENTION

The increasing Internet traffic and the increased complexity and use ofweb applications has forced network providers and network infrastructuremanagers to seek enhanced transmission speeds for network equipment. TheTIA/EIA set up a high-performance cabling category to fulfill thisrequirement often referred to as CAT 6.

Such high-performance cabling uses a format with RJ 45 jacks and plugs.The agreed to format for the lines at such a connector involves a linewith a center pair of conductors at the connector and a split pair ofconductors at the connector. One conductor contact of the split pair ison each side of the center pair conductor contacts. When such an RJ 45plug mates with an RJ 45 jack with signals at such high frequencies (asper the standard), the split pair will suffer a significant Near EndCross Talk (NEXT) problem from the other pairs.

It is known that electrical signals of one pair of conductors may becoupled onto the other pair of conductors for compensating or cancelingcrosstalk. JP 64 [1989] 20690 (JP '690) discloses a modular telephonejack with a crosstalk prevention function where a capacitor is installedwithin a housing. A printed circuit board has traces connected to thecapacitors and also connected between insulation displacement contacts(IDCs) and contact springs of the jack. In FIG. 4 an arrangement isshown wherein the traces are used to form a capacitor, to counteract thecrosstalk. These traces cross each other with left to right crossing.Discrete capacitors may also be connected between transmission paths tocompensate crosstalk (FIG. 3). JP '690 shows the use of both discretecapacitors connected to interconnecting traces of a circuit board toreduce crosstalk in jacks as well as the positioning of theinterconnecting traces of the circuit boards providing capacitiveinteraction to reduce crosstalk.

U.S. Pat. No. 5,997,358 (US '358) discloses an electrical connector thatachieves high transmission performance (CAT 6) by providing compensationstages for introducing predetermined amounts of compensation betweenpairs of conductors. Two or more of such compensation stages areprovided. A first compensation stage adds a compensation signal that istime delayed with respect to the other compensation stages. In the firststage compensating crosstalk is introduced between the pairs of a firstpredetermined magnitude and phase in a given frequency. In a secondstage, compensating crosstalk is introduced between pairs that has asecond magnitude and phase in a given frequency. The first stagemagnitude is larger than the offending crosstalk and the second stagereintroduces the offending crosstalk. US '358 uses multiple compensationstages to compensate for phase issues because, at high frequencies,compensating crosstalk cannot be introduced that is exactly 180° out ofphase with the offending crosstalk.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a connector jack thatincludes spring contacts with conductor pairs for plural lines definingan RJ style contact interface for connection with an RJ style plug andwith interconnecting circuitry on a printed circuit board and withcrosstalk compensation provided to achieve high levels of throughput andperformance.

It is a further object of the invention to provide a solution to thedesire to provide a high performance jack where the signal path betweenplug contact and the terminal (at which compensation may be easilyapplied) is preferably limited to 6.2 mm and to avoid shortening thespring contacts below 1.5 mm such that the spring contacts have theproper strength under a predefined deflection.

According to the invention, a modular jack is provided comprising a bodywith a support portion and a plug receiving portion defining an opening.A circuit board is mounted to the support portion to position thecircuit board relative to the plug receiving portion. The circuit boardhas interconnecting conductor circuit traces respectively extending fromspring contact termination locations. A signal path is provided from amated plug blade through a supported contact spring and a terminalelement terminated to the contact termination location.

The jack advantageously mates with a plug having plug contact bladeswherein each the terminated spring contact conductor is located near aplug contact blade position of a mated plug. The terminal element mayadvantageously be disposed tangent to a rotation circle of the supportedspring contact conductor.

According to another aspect of the invention, an electrical connectorjack is provided comprising a body with a support portion and a plugreceiving portion defining an opening. A circuit board is mounted to thesupport portion to position the circuit board relative to the plugreceiving portion. The circuit board has interconnecting conductorcircuit traces respectively extending from spring contact terminationlocations. A plurality of terminated spring contact conductors areprovided, each terminating at a respective one of the spring contacttermination locations. Each of the terminated spring contact conductorshas a contact zone. A plurality of supported spring contact conductorsare supported by the body and extend therefrom. The supported springcontact conductors each have a plug contact zone and a terminated springcontact conductor zone. With contact of the plug contact zone with aplug, the supported spring contact conductors are respectively incontact with a respective contact zone of the terminated spring contactconductors providing a transmission path from the plug to the circuittraces of the circuit board.

At least one of the supported spring contact conductors and theterminated spring contact conductors may advantageously be positioned toform a capacitance with a respective nonadjacent neighboring supportedspring contact conductor and terminated spring contact conductor forcompensating coupling at the plug contact zone between adjacentsupported spring contact conductors and terminated spring contactconductors.

The adjacent spring contact termination locations may advantageously bespaced apart or offset on the circuit board.

The adjacent supported spring contact conductors and adjacent terminatedspring contact conductors may advantageously be shaped differently oroffset angularly or positionally to avoid coupling of the adjacentsupported spring contact conductors and the adjacent terminated springcontact conductors.

The adjacent terminated spring contact conductors may advantageously beoffset to avoid coupling with adjacent terminated spring contactconductors.

Contacting the terminated spring contact conductors and supported springcontact conductors provide a conductive path from the plug contact zoneto a respective spring contact termination location and have aconductive path that is 6.2 mm or less.

With contact between the terminated spring contact conductors and thesupported spring contact conductors a conductive path is provided fromthe plug contact zone to a respective spring contact terminationlocation. Pairs of conductive paths form part of transmission lines.

A first/second crosstalk compensation element providing a crosstalkcompensation signal between a first interconnecting conductor of oneline and a second interconnecting conductor of another line mayadvantageously be provided. A second/first crosstalk compensationelement providing a second/first crosstalk compensation signal between asecond interconnecting conductor of the one line and a firstinterconnecting conductor of the another line may advantageously beprovided. Each crosstalk compensation element may advantageously beapplied at or closely adjacent to a respective termination location.

Providing crosstalk compensation between lines at a location close tothe source of the crosstalk coupling is advantageous (see U.S. patentapplications Ser. No. 11/360,101 filed Feb. 23, 2006 and 11/369,257filed Mar. 7, 2006, incorporated herein by reference). Such anintroduction of a crosstalk compensation signal may be in the form ofsingle compensating coupling applied along the transmission paths aswell as staged compensating coupling applied along the transmissionpaths. Such single phase (one location along the transmission paths) andmulti-phase (plural locations along the transmission paths) crosstalkcompensation is applied at a distance from the source of the crosstalkcoupling. The invention allows a minimization of the distance from thesource of the crosstalk coupling to the first or only crosstalkcompensation between paths of two transmission lines. This is done whilealso providing good spring contact force for good plug connectionattributes.

The invention provides the spring contact function and the terminalfunction by different elements. A conventional contact spring, whichcould afford the predefined deflection requirement, is used to contactboth with the mated module plug (RJ type plug) and the terminal element(terminated spring contact conductor). The terminal element is used topass the signal to a PCB. By locating the terminal element very close tothe plug contact point, it is possible to reduce the signal path lengthbetween the plug and the PCB terminal.

The design may advantageously locate the terminal element almost tangentto the rotation circle of the supported contact spring so that thedeflection of the terminal element or the supported contact spring isminimized.

The terminal element may be parallel to the plug access axis so that thesignal traveling length from the plug to PCB is reduced when a plug ismated.

The terminal element may advantageously further form a capacitor withthe supported contact spring and neighboring nonadjacent terminalelements and supported contact springs to compensate the offendingsignal due to the crosstalk between plug blades and adjacent supportedspring contacts.

The various features of novelty which characterize the invention arepointed out with particularity in the claims annexed to and forming apart of this disclosure. For a better understanding of the invention,its operating advantages and specific objects attained by its uses,reference is made to the accompanying drawings and descriptive matter inwhich preferred embodiments of the invention are illustrated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the drawings in particular, the invention comprises ahigh-performance jack. A first embodiment is shown in FIG. 1 with thehigh-performance jack generally designated 10. The high-performance jackincludes a jack body formed with a base part 12 connected to aninsulation displacement contact (IDC) part 16 and a cover part 14. FIG.2 shows the structure with the cover part 14 removed. The cover part 14defines a plug opening 24 into which a plug 32 may be inserted in a pluginsertion direction (having a plug insertion direction axis). The IDCpart 16 provides support for IDCs 18 terminated to a circuit board 35.The IDC part 16 has slots 19 for terminating wires in the IDCs 28. Thisregion may be covered with a cover part 30 (FIG. 3).

The base part 12 supports the circuit board 35 and also supports aplurality of supported spring contact conductors designated 20 and 22.As can be seen in FIGS. 4 and 5, the supported spring contact conductors20 and 22 are fixed at one end to the base part 12 and extend as acantilever spring from the fixed support point. The supported springcontact conductors 20 all have the same shape and the supported springcontact conductors 22 all have the same shape. The shape of the sets ofconductors 20 advantageously may be different from the shape of thesupported spring contact conductors 22. The spring contact conductorsare arranged with every other supported spring contact conductor 20, 22being of the shape of supported spring contact conductor 20 and everyother supported spring contact conductor being the shape of supportedspring contact conductor 22. With this there is less coupling betweenadjacent supported spring contact conductors 20 and 22. Additionally, asall of the nonadjacent neighboring supported spring contact conductors22 have the same shape, these neighboring conductors 22 form capacitorsbased on some signal coupling caused by the similar shape and positionof the nonadjacent supported spring contact conductors 22. As all of thenonadjacent supported spring contact conductors 20 have the same shapethese form capacitors based on some signal coupling caused by thesimilar shape/position of the nonadjacent supported spring contactconductors 20. This can provide some compensation for crosstalk thatoccurs. This crosstalk particularly occurs at the plug contacts 33 andbetween adjacent supported spring contact conductors 20 and 22 at a plugcontact region 21 of the supported spring contact conductors 20 and aplug contact region 23 of the supported spring contact conductors 22.

As can best be seen in FIG. 3 two different types of terminated springcontact conductors 40 and 42 are provided. Each of the terminated springcontact conductors 40 and 42 terminate at spring contact terminationlocations 34 on printed circuit board 35. These termination locations 34are offset relative to adjacent termination locations 34 providing lesscoupling between adjacent spring contact conductors 40 and 42. Further,all of the terminated spring contact conductors 42 have the same shapeand all of the terminated spring contact conductors 40 have the sameshape. Based on the offset and the shaping, a capacitance is formedbetween nonadjacent neighboring terminated spring contact conductors 40.A capacitance is also formed between nonadjacent neighboring terminatedspring contact conductors 42. This provides some compensation forcrosstalk that occurs between adjacent supported spring contactconductors in the plug contact regions 21 and 23 (and that caused fromthe plug contacts 33).

Based on the shape and position of the spring contacts 20, 22, 40 and42, with a RJ type plug 32 in a contact position, inserted into theopening 24 (shown in FIGS. 4 and 5), each of the contacts 20 is movedinto electrical contact with a contact 40 whereby a contact surface 25electrically contacts a contact surface 47 to provide a transmissionsignal path. In a similar manner with a plug 32 inserted in the contactposition, each spring contact 22 is moved into electrical contact with aspring contact 42 whereby a contact surface 27 electrically contacts acontact surface 44 to provide a transmission signal path. The movementof the supported spring contact conductors 20, 22 is based on the shapeof these and the insertion direction of the plug to provide each thesupported spring contact conductors 20, 22 with a rotation circle ormovement path. The terminal spring contacts 40 and 42 is advantageouslysupported almost tangent to or tangent to the respective rotationcircle. The terminal spring contacts 40 and 42 may be almost parallel tothe plug access or insertion axis.

With this construction, the overall transmission signal path from theplug contact zone 23 to the termination locations 34 on the circuitboard may be made short. The supported spring contacts 20, 22 and tosome degree the terminated spring contacts 40 and 42 contribute to theplug contact force required. Transmission paths of determined couplingand length may be advantageously provided without jeopardizing thespring contact force which is required for proper mating with the plug32.

FIGS. 6A and 6B respectively show a first and second side of the circuitboard 35. The circuit board 35 has the termination locations 34 for eachof the transmission paths numbered 1 through 8. The circuit board 35 hasinterconnecting conductor circuit traces 37 respectively extending fromspring contact termination locations 34 to IDC termination locations 39.The conductors are provided to present transmission paths from springcontact conductors 40 and 42 to the IDCs 18. Two transmission pathstogether provide a transmission line. In this case, the paths 1 and 2form a transmission line, the paths 3 and 6 form a transmission line,the paths 4 and 5 form a transmission line and the paths 7 and 8 form atransmission line. The split paths 3 and 6 are on each side of the paths4 and 5, presenting crosstalk coupling problems at the plug and in theplug contact zone. Other crosstalk occurs between adjacent plug contactsand in adjacent supported spring contact conductors 20 and 22 in theplug contact zone. A first compensation element 46 is provided on thecircuit board for compensation between the transmission paths 4 and 6respectively of the transmission lines 3, 6 and 4, 5. A firstcompensation element 86 is provided on the circuit board forcompensation between the transmission paths 8 and 6 respectively of thetransmission lines 3,6 and 7, 8. A first compensation element 13 isprovided on the circuit board for compensation between the transmissionpaths 1 and 3 of respectively of the transmission lines 3,6 and 1, 2.These first compensation elements 46, 86 and 13 are advantageouslyconnected to the termination locations 34 of the respective transmissionpaths, providing the compensation at a short distance from the locationthe crosstalk is introduced.

FIG. 7 shows an alternative embodiment according to the invention with ahigh-performance jack generally designated 50. The high-performance jack50 includes a jack body formed with a base part 52 (see FIG. 8)connected to an insulation displacement contact (IDC) part 56 housingIDCs 58 and a cover part 54. The IDC part 56 has slots 66 forterminating wires to IDCs. FIG. 8 shows the structure with the coverpart 54 removed showing the base part 52 supporting a plurality ofsupported spring contact conductors designated 60 and 62. As can be seenin FIG. 10, the supported spring contact conductors 60 and 62 are fixedat one end to the base part 52 and extend as a cantilever spring fromthe fixed support point. The supported spring contact conductors 60 allhave the same shape and the supported spring contact conductors 62 allhave the same shape with the shape of the sets of conductors 60different from the shape of the supported spring contact conductors 62.The spring contact conductors 60, 62 are arranged alternating betweensupported spring contact conductors 60 and 62 providing less couplingbetween adjacent supported spring contact conductors 60 and 62.Additionally, as all of the nonadjacent neighboring supported springcontact conductors 62 have the same shape, these neighboring conductorsform capacitors. The same is the case with the nonadjacent neighboringsupported spring contact conductors 60 to provide some compensation forcrosstalk that occurs (at the plug contacts and between contactconductors at a plug contact regions 61 and 63).

As can best be seen in FIG. 9 two different types of terminated springcontact conductors 80 and 82 are provided. Each of the terminated springcontact conductors 80 and 82 terminate at spring contact terminationlocations 34 on printed circuit board 75. These termination locations 34are offset relative to adjacent termination locations 34 providing lesscoupling between adjacent spring contact conductors 80 and 82. Further,all of the terminated spring contact conductors 82 have the same shapeand all of the terminated spring contact conductors 80 have the sameshape. In this embodiment with the offset of the termination locations34, the basic shape of the spring contact conductors 80 and 82 is thesame. Based on the offset, a capacitance is formed between nonadjacentneighboring terminated spring contact conductors 80 and a capacitance isformed between nonadjacent neighboring terminated spring contactconductors 82. This provides some compensation for crosstalk that occursbetween adjacent supported spring contact conductors plug contact region61 and plug contact region 63 (and compensation for crosstalk thatoccurs between plug contacts).

Based on the shape and position of the spring contacts 60, 62, 80 and82, with a plug 32 in a contact position, inserted into the opening 64,each of the contacts 60 is moved into electrical contact with a contact80 whereby a contact surface 65 electrically contacts a contact surface84 to provide a transmission signal path. In a similar manner with aplug 32 inserted in the contact position, each spring contact 62 ismoved into electrical contact with a spring contact 82 whereby a contactsurface 67 electrically contacts a contact surface 86 to provide asignal transmission signal path. The movement of the supported springcontact conductors 60, 62 is based on the shape of these and theinsertion direction of the plug to provide each of the supported springcontact conductors 60, 62 with a rotation circle or movement path. Theterminal spring contacts 80 and 82 is advantageously supported almosttangent to or tangent to the respective rotation circle. The terminalspring contacts 80 and 82 may be almost parallel to the plug access orinsertion axis.

With this construction, the overall transmission signal path from theplug contact zone 61, 63 to the termination locations on the circuitboard may be made short. The supported spring contacts 60, 62 and tosome degree the terminated spring contacts 80 and 82 contribute to theplug contact force required. Transmission paths of determined couplingand length may be advantageously provided without jeopardizing thespring contact force which is required for proper mating with the plug32.

FIGS. 11A and 11B respectively show a first and second side of thecircuit board 75. The circuit board 75 has the termination locations 34for each of various transmission paths numbered 1 through 8. The circuitboard 75 has interconnecting conductor circuit traces 37 respectivelyextending from spring contact termination locations 34 to IDCtermination locations 39. The transmission paths numbered 1 to 8 arefrom spring contact conductors 60 and 62 to the IDCs 58. Twotransmission paths together provide a transmission line. In this case,the paths 1 and 2 form a transmission line, the paths 3 and 6 form atransmission line, the paths 4 and 5 form a transmission line and thepaths 7 and 8 form a transmission line. The split paths 3 and 6 are oneach side of the paths 4 and 5, presenting problems as to crosstalkcoupling at the plug and in the plug contact zone. Other crosstalkoccurs between adjacent plug contacts and in adjacent supported springcontact conductors 60 and 62 in the plug contact zone. A firstcompensation element 46 is provided on the circuit board forcompensation between the transmission paths 4 and 6 respectively of thetransmission lines 3,6 and 4, 5. In this embodiment another firstcompensation element 53 is provided on the circuit board forcompensation between the transmission paths 5 and 3 respectively of thetransmission lines 4, 5 and 3, 6. A first compensation element 86 isprovided on the circuit board for compensation between the transmissionpaths 8 and 6 respectively of the transmission lines 3,6 and 7, 8. Afirst compensation element 13 is provided on the circuit board forcompensation between the transmission paths 1 and 3 of respectively ofthe transmission lines 3,6 and 1, 2. These first compensation elements46, 53, 86 and 13 are advantageously connected to the terminationlocations 34 of the respective transmission paths, providing thecompensation at a short distance form the location the crosstalk isintroduced.
